What a buyer needs to know

$159.99, SFX, 750W. ⚠ IT SHIPS EXACTLY 2× 8-PIN SOCKETS. This is the spec that catches people, because an SFX PSU advertised as '4× 8-pin' usually means TWO CABLES WITH PIGTAILS, not four sockets. COUNT MODULAR SOCKETS, NEVER CABLE ENDS. SilverStone's own guidance is that one 8-pin cable is rated 150W and a card above 225W should use two or three SEPARATE PCIe cables (the warranty conclusion people quote is an inference from that, not a sentence SilverStone wrote). 🛑 SO: A 3× 8-PIN GPU IS A HARD NO ON THIS UNIT. The RTX 3090 ROG Strix, FTW3 and Gaming X Trio are all 3× 8-pin cards; feeding a 350W GA102 off two cables with a pigtail is exactly what not to do. ASUS themselves spec 850W for their own 3090s, above NVIDIA's 750W floor. If you are building a 3090, you want ~850W and enough SOCKETS — not this. BUY THE SF850 INSTEAD IF YOU CAN: at Newegg it is $157.99, i.e. CHEAPER THAN THIS 750W UNIT, with headroom for a future GPU. (It is not in this catalog yet only because CATALOG.md does not publish its socket count — see the PSU note in scripts/catalog.ts.) And note the channel: Corsair's own store is the most expensive place to buy a Corsair PSU — $224.99 direct vs $157.99 at Newegg for the identical SKU.
