Power supplies and CPU coolers are the two parts first-time builders most often either skimp on or overspend on, and both mistakes get expensive. This guide covers five solid picks from about $30 for a basic air cooler to $110 for a fully modular power supply that can carry a mid-range build for years.
A power supply is not a place to save $15 by buying an unbranded unit — a cheap, poorly regulated PSU can damage every other component in the case if it fails. Coolers matter less for catastrophic failure but make the difference between a build that’s pleasant to sit near and one that sounds like a hair dryer under load.
Wattage headroom is worth planning for even on a tight budget. A PSU running near its rated maximum wears out faster and runs hotter than one with 20-30% of capacity to spare, so it’s usually worth sizing up one tier from whatever an online calculator suggests for the exact parts list.
1. Corsair RM750e — best mid-range fully modular PSU
Corsair’s RM750e delivers 750 watts of 80 Plus Gold-rated power with fully modular cabling, so builders only plug in the cables their case actually needs, keeping airflow cleaner. It’s a safe pick for most single-GPU gaming builds with headroom for a future upgrade. Street price runs $85-$110.
2. EVGA 500 BQ — best budget non-modular PSU
For a lower-power build without a dedicated graphics card, EVGA’s 500 BQ covers the basics with 80 Plus Bronze efficiency at a price that leaves more of the budget for the CPU or storage. Non-modular cabling means a bit more cable clutter, but it’s a non-issue in most budget cases. Budget $35-$50.
3. Cooler Master Hyper 212 — best budget air cooler
The Hyper 212 has been a first-build staple for over a decade because it handles mainstream CPUs at stock and mild overclock speeds for a fraction of what liquid cooling costs, with straightforward mounting hardware that’s hard to mess up. Expect $30-$45.
4. ARCTIC Liquid Freezer III 240 — best budget AIO liquid cooler
For builders running a higher-end CPU that runs hot under sustained load, the Liquid Freezer III’s 240mm radiator delivers cooling performance that competes with coolers costing twice as much, thanks to Arctic’s efficient pump and fan design. Look for $75-$100.
5. be quiet! Pure Power 12 M — best quiet-focused PSU
be quiet! built its reputation on low-noise components, and the Pure Power 12 M pairs a semi-fanless mode at low loads with modular cabling, making it a strong pick for anyone building a PC that’ll sit in a bedroom or shared living space. Budget $70-$95.
6. Noctua NH-U12S Redux — best air cooler for a quieter, higher-end build
Noctua’s fans are widely regarded as the quietest on the market, and the NH-U12S Redux brings that reputation to a lower price point than Noctua’s flagship coolers while still handling mid-to-high-end CPUs comfortably. It’s a strong pick for anyone who cares more about noise than shaving off the last few degrees. Expect $45-$65.
How to get the best price
- Set a price-tracking alert on the exact wattage and model you need, since PSU and cooler prices fluctuate with component sales cycles tied to new CPU and GPU launches.
- Buy PSU and cooler together in a bundle listing when a retailer offers one, since combo discounts on non-competing parts are common and don’t affect warranty coverage.
- Check for mail-in rebates on Corsair and EVGA power supplies, which often knock $10-$20 off during back-to-school and holiday sales windows.
- Avoid the cheapest unbranded PSU listings entirely regardless of price, since a failure can take other components down with it and voids most warranties on the rest of the build.
- Register the warranty on both the PSU and cooler as soon as the build is complete, since Corsair and be quiet! both offer multi-year coverage that’s easy to forget to activate.
Neither the power supply nor the cooler will show up in a benchmark chart, but skimping on either is the fastest way to turn a budget build into an expensive repair. Spend proportionally: a mid-range PSU with headroom and a cooler rated for slightly more heat than the CPU produces will outlast several GPU upgrades, and both parts can usually be carried over into the next build rather than replaced alongside the CPU and GPU.
