£3000 rtx 4090 bulid

[widow-maker]

Been looking around for a £3000 rtx 4090 build and have come up with the following, have chosen a budget case to attempt to keep the prices down

CORSAIR RM750E 750 WATT POWER SUPPLY £129
IONZ KZ-Z DEEP SPACE TOWER PC CASE £80
MSI VGA RTX 4090 VENTUS £1740
INTEL ICORE I7-13700K £415
CORSAIR ICUE H100I RGB ELITE CPU COOLER £149
SAMSUNG 980 PRO 2TB £180
G.SKILL TRIDENT Z5 RGB 32GB DDR5 £155
GIGABYTE Z790 AORUS ELITE AX INTEL Z790-MOTHERBOARD £305

All these prices are from amazon so maybe I will be able to find them slightly cheaper once i order them but the whole package is around £3000 any suggestions would be appreciated.

Thanks

That psu is insufficient for your proposed build, you should be looking at 1000w as a minimum and if you are buying from new you may as well get an ATX 3.0 standard psu.

i am not sure if the new corsair shift psus will work with your selected case, they have changed the side the cables come out of so it will not work well with some cases.

That 1200w is only £10 more than the 1000w so no brainer to get the higher capacity. Also in stock is the -

These new psus are a lot more expensive but when you consider the price of a 4090 they are a bargain and will outlast that component as well.

750W is right on the limit of what you need for those components. If you don't overclock, and don't do anything that maxes out the CPU and GPU simultaneously you'd probably be fine but I'd go with 850W or 1000W to be safe. Definitely 1000w if you will be overclocking, 1200W would be overkill but if it doesn't cost much extra then sure. I run an 11700K and 3080Ti both overclocked on an 850W PSU and have zero issues.

In terms of storage you might get slightly better value getting only a 1TB samsung 980 pro and then a 1TB or 2TB PCIe3 NVMe drive like a WD SN570 or similar. You only really need PCIe4 speeds for the OS and some specific games that benefit from faster storage speeds (Rust comes to mind, initial load is much faster), most games will be fine at PCIe3 speeds and won't benefit any from PCIe4 speeds, any potential benefit will only be to loading times rather than fps.
