Every mid range PC build hits the same wall at checkout: the graphics card and CPU get the budget, and the power supply becomes an afterthought. Then the random restarts start, the fans whine under load, or worse, a cheap unit fails and takes components down with it. The problem is that PSU marketing is a wall of certifications and wattage claims, and it’s genuinely hard to tell a $40 unit that will run reliably for years from one that will brown out the first time your GPU spikes.
We put together this roundup to cut through that noise. All eight units below cost less than $70, several cost less than $40, and each one comes from a brand with a real track record in the budget segment. Whether you’re building a mid tower gaming rig around a 65W CPU and a mid range GPU, or upgrading an aging office desktop that groans under load, there’s a tested option here that fits your case, your rail requirements, and your wallet.

How We Picked
To keep this list honest, we set hard boundaries. Every PSU here had to cost under $70, be a standard ATX form factor that fits any mid tower case, and come with active PFC for stable power draw from the wall. We also required either an 80 Plus certification of some level or a full protection suite (over voltage, under voltage, over power, and short circuit protection) so you’re not gambling with your components.
Beyond that, we weighed three factors: warranty length as a proxy for manufacturer confidence, fan noise at typical loads, and the connector set — PCIe power connectors for the graphics card, enough SATA leads for modern storage, and a native EPS CPU cable. Prices listed are the current advertised prices and can fluctuate, so treat them as ranges; a sale can drop any of these by $5 to $10. We did not conduct our own bench stress testing, so all efficiency ratings and protection features cited come directly from manufacturer specifications.
The 8 Best Picks
1. Thermaltake Smart 500W 80+ White Certified PSU (PS-SPD-0500NPCWUS-W)
This is the dependable baseline pick for a build without a discrete graphics card or with a low power GPU. The Smart 500W delivers its rated 500W as continuous power rather than peak, which matters — many no-name budget PSUs quote peak numbers they can only hold for seconds. The 120mm ultra quiet fan keeps noise reasonable, and the unit complies with ATX 12V V2.3 and EPS 12V standards with active PFC.
- True continuous 500W output at an accessible $39.99 price
- 80 Plus White certification for modest efficiency gains at typical loads
- Fan can get audible under sustained heavy loads
When to skip it: if you’re pairing a 65W CPU with anything beyond an entry level GPU, step up to the 600W version for connector and headroom comfort.
2. Thermaltake SMART 600W ATX 12V V2.3/EPS 12V (PS-SPD-0600NPCWUS-W)
The 600W Smart is the sweet spot in Thermaltake’s budget line for mid range builds. That extra 100W over the 500W model means comfortable headroom for a mid range graphics card plus a modern CPU, without pushing the unit into its least efficient load range. It’s 80 Plus certified, uses active PFC, and follows the same ATX 12V V2.3/EPS 12V platform as its siblings, with a 120mm fan handling cooling.
- 600W of certified power for just $42.99 — excellent dollars-per-watt
- Active PFC design for stable input power handling
- Non-modular cabling gets cluttered in compact cases
When to skip it: if your build targets Gold efficiency or you want the longest possible warranty, the Toughpower GX2 below is the better long term buy.
3. Apevia SPIRIT600W Spirit 600W ATX Power Supply
Apevia’s Spirit 600W is the value play of this entire list. At $33.99 it undercuts everything else here while still offering a 600W output, a 120mm cooling fan, and — critically — all the standard protection circuits: over voltage, under voltage, over power, and short circuit protection. For a first build, a dorm PC, or a budget gaming rig where every dollar counts, this is the definition of getting the essentials without frills.
- 600W for just $33.99, the lowest price on the list
- Full protection suite including OVP, UVP, OPP, and SCP
- No 80 Plus efficiency certification listed
When to skip it: if efficiency on your electric bill and lower heat output matter to you, spend the extra few dollars on a Bronze certified unit.
4. Thermaltake Smart 700W 80+ White Certified PSU (PS-SPD-0700NPCWUS-W)
If your mid range build leans ambitious — a power hungry CPU, plans for a future GPU upgrade, or a stack of drives — the Smart 700W gives you 200W more than the 600W model for just $12 more. Like the rest of the Smart line, it’s rated for continuous power, carries 80 Plus White certification, runs on the ATX 12V V2.3/EPS 12V platform with active PFC, and uses an ultra quiet 120mm fan.
- 700W continuous output for only $54.99
- Plenty of headroom for future GPU upgrades
- 80 Plus White is the entry level efficiency tier
When to skip it: if your system realistically draws under 400W, you’re paying for wattage you’ll never use — drop to the 600W and pocket the difference.
5. MSI MAG A650BN 650W Power Supply
The MAG A650BN is our overall top pick, and the 5 year warranty is the reason. No other budget brand here backs its product that long at this price. You get 650W with 80 Plus Bronze certification, a compact non-modular design that fits smaller cases more easily than many competitors, a low-noise fan profile, and MSI’s active PFC design. At $63.99 it’s the priciest unit here, but the warranty and brand support justify it for a build you plan to keep running for years.
- 5 year warranty — the longest coverage in this roundup
- 80 Plus Bronze efficiency in a compact chassis with a quiet fan
- Highest price on the list at $63.99
When to skip it: if you’re building the absolute cheapest rig possible, the Apevia or ARESGAME options save you $25 or more.
6. ARESGAME AGV Series 500W Power Supply
The AGV 500W hits a rare combination: 80 Plus Bronze certification and a 5 year warranty for just $37.99. That makes it the cheapest way into certified Bronze efficiency in this roundup, and the warranty matches MSI’s despite costing $26 less. The non-modular design includes the standard ATX connector set for a mainstream build, and it’s a natural fit for a mid tower gaming PC with a mid range GPU.
- 80 Plus Bronze certified at just $37.99
- 5 year warranty matching units that cost far more
- 500W may be tight for high draw GPU and CPU combinations
When to skip it: if your graphics card recommendations call for 550W or more, move up to a 600W or 650W option.
7. Thermaltake Toughpower GX2 80+ Gold 600W (PS-TPD-0600NNFAGU-2)
The Toughpower GX2 is the efficiency flagship of this list and the only Gold certified unit here. At $59.99 you get 600W of continuous power, SLI and CrossFire readiness with dual PCIe support, and compliance with newer ATX 12V V2.4 and EPS V2.92 standards — a step up from the V2.3 platforms used elsewhere on this list. Thermaltake backs it with a 5 year warranty, and the non-modular cabling keeps the price reasonable.
- 80 Plus Gold efficiency cuts wasted heat and electricity
- SLI/CrossFire ready with a 5 year warranty
- Dual GPU readiness is largely unnecessary for modern single GPU builds
When to skip it: if you’ll never approach 600W of draw, Bronze units like the ARESGAME deliver most of the practical value for $22 less.
8. Apevia ATX-SP700 Spirit 700W ATX Power Supply
The Spirit 700W is the wattage bargain of the group: 700W of output, a 120mm fan, and Apevia’s full protection suite for $36.99 — less than the 500W Thermaltake. Like its 600W sibling, it includes over voltage, under voltage, over power, and short circuit protection, making it a surprisingly safe choice for a high wattage budget build, a system with multiple drives, or a rig you plan to upgrade graphics cards into later.
- 700W output for just $36.99 — unmatched watts per dollar
- All standard protection circuits included
- No 80 Plus certification listed, so expect average efficiency
When to skip it: if your build draws modest power, buying 700W you won’t use makes no sense — prioritize efficiency certification instead.
Buying Guide
How Much Wattage Do You Actually Need?
Count your components, don’t guess. A modern mid range CPU draws 65W to 125W, a mid range graphics card typically needs 150W to 250W, and the rest of a system — motherboard, drives, fans, RAM — adds another 50W to 80W. Add those up and leave 30 to 40 percent headroom so the PSU runs in its efficient, quiet range. For most mid range builds, that lands you squarely in the 500W to 650W window that most of this list occupies. Buying 700W “to be safe” when your system draws 300W wastes money and can actually run the PSU at inefficient low loads.
Efficiency Certifications, Explained
The 80 Plus rating measures how efficiently a PSU converts wall AC power into DC power for your components, and it matters for both your electric bill and your case temperatures. An 80 Plus White unit converts at least 80 percent at typical loads; Bronze is slightly better, and Gold units like the Toughpower GX2 reach roughly 87 to 92 percent depending on load. On a mid range gaming PC, the difference between White and Gold is real but modest — think a few dollars a year in electricity. The bigger practical benefit of higher efficiency is less waste heat inside your case, which means a cooler, quieter system.
Warranty and Protections Are Not Optional
A power supply is the one component that can damage everything else when it fails, so treat warranty length and protection circuits as non-negotiable. Look for over voltage protection (OVP), under voltage protection (UVP), over power protection (OPP), and short circuit protection (SCP) — both Apevia units include the full suite, and MSI and ARESGAME back their units with 5 year warranties versus the standard coverage elsewhere. A 5 year warranty signals the manufacturer expects the unit to survive half a decade of daily use, which is exactly what you want from the part powering everything else in your build.
Our Verdict
If you want one recommendation, buy the MSI MAG A650BN at $63.99. Its 80 Plus Bronze efficiency, compact design, low-noise fan, and above all its 5 year warranty make it the safest long term investment for a mid range build, and the price premium over the rest of this list is small. If budget is the absolute priority, the ARESGAME AGV 500W at $37.99 delivers Bronze certification and that same 5 year warranty for a fraction of the cost, making it the best pure value pick. For maximum wattage on a shoestring, the Apevia ATX-SP700 at $36.99 is hard to beat. And if you want the cleanest efficiency, the Thermaltake Toughpower GX2 600W is the only Gold certified option here. Whichever you choose, any of these eight units is a meaningful step up from the anonymous no-name PSU lurking in a bargain bin — and by 2026 standards, all of them are legitimately capable of powering a modern mid range PC for years.
FAQ
Is 500W enough for a mid range gaming PC?
For most mid range builds, yes. A system with a 65W to 95W CPU and a graphics card in the 150W to 200W class typically draws 250W to 350W under gaming load, leaving comfortable headroom on a quality 500W unit like the Thermaltake Smart 500W or ARESGAME AGV 500W. Check your GPU manufacturer’s recommended PSU wattage before buying, and step up to 600W or 650W if the recommendation calls for it or if you plan a future graphics upgrade.
Do I need a modular power supply?
Not necessarily. Modular PSUs let you detach unused cables for cleaner cable management, but they cost more at every wattage. All eight units here are non-modular, which is standard in the budget segment and perfectly fine in a full or mid tower case with room to stash extra cables behind the motherboard tray. Prioritize wattage, efficiency certification, and warranty over modularity when money is tight.
What does 80 Plus White mean compared to Bronze or Gold?
These ratings describe conversion efficiency at typical loads. 80 Plus White units convert at least 80 percent of wall power into usable DC power at 20, 50, and 100 percent load; Bronze is marginally better, and Gold units reach roughly 87 to 92 percent. The practical difference for a mid range build is a few dollars a year in electricity and slightly less heat dumped into your case. White and Bronze are entirely acceptable at this price point; Gold, as on the Toughpower GX2, is a bonus.
How long should a budget power supply last?
A well made budget PSU from a reputable brand should last 5 to 10 years of typical use, which is why the 5 year warranties on the MSI MAG A650BN, ARESGAME AGV 500W, and Toughpower GX2 matter — the manufacturer is staking real money on that lifespan. Warning signs of a failing unit include random shutdowns under load, coil whine that worsens over time, crackling noises, or failure to power on. Replace the PSU at the first sign of trouble rather than gambling with your other components.
