Power supplies deals: the real ones
We check UK prices for every power supplie we've reviewed every hour, and compare each one with what it has actually sold for, not the shop's “was” price. One only shows here as a deal if it's genuinely cheaper than usual.
Price history is still building: drops show here once we've tracked a price for a week

Before you buy power supplies in a sale
How do you know a deal is real?
We check UK prices for every power supplie we've reviewed every hour and keep the history. A price counts as a drop only when it's below what the product has actually sold for over the last month, not below a shop's "was" price, which is often made up.
How many watts do I need?
Add up your processor and graphics card power and leave about a third spare. Most single-graphics-card builds are fine with 750 to 850 W.
Does it need a 12V-2x6 cable?
Recent high-end graphics cards use it. A power supply with the cable built in is tidier and safer than an adaptor.
“Usually” is the median of the lowest daily UK price over the last month, or the typical price we found when researching a product we haven't tracked for a week yet. Prices change, so check the price and delivery date with the shop before you buy. Links to retailers may earn us a commission, which never affects which product we pick.
