[FullMetalSyn]

Hi i'm new to pc building and needed some help i built a new pc a week ago, it booted up fine and was working for 3 days with zero issues, my pc was in sleep mode the night before then next morning i noticed all the mobo lights and ram were off and the pc had zero life to it and wouldnt turn on at all no ezled light errors, just dead also my electricity ran out early hrs of the morning so not sure if that was the cause of it, i troubleshooted everything i could find online with no luck i have returned the mobo and psu for a refund and replacing them both. Im just wondering if this new mobo will be compatible with my current build that i'm thinking of buying below is the details of the build. This is the new PSU and motherboard I'm looking on getting is this:-

be quiet straight power 11 750 w 80+ platinum fully modular PSU

​

My current build is this:-
CPU - i5 13600k
Motherboard - MSI Z790 Gaming Pro WIFI DDR5
Ram - CORSAIR VENGEANCE RGB DDR5 RAM 32GB 6000Mhz CL36
SSD - Samsung 980 PRO M.2 NVMe SSD
GPU - MSI Geforce RTX 4070 VENTUS 2X 12G OC
PSU - MSI MPG A750GF 750 w 80 plus gold
CASE - Fractal Design Meshify 2 Lite

It is compatible, but personally I'd want an ATX3.0/PCIE5 PSU with a 10 year warranty, since 5 is rather mediocre nowadays.

any recommendation of a psu i could get thanks.

If you want platinum, maybe the PF3.

If you don't care about ATX3.0/PCIE5, then the GX-750.

Otherwise, A850G PCIE5, review here of A1000G PCIE5.

My basket at OcUK:

• 1 x MSI MPG A850G PCIE5 UK PSU 850W 80 Plus Gold Modular Power Supply (SKU: CA-00Y-MS) = £139.99
• 1 x Thermaltake Toughpower PF3 750W ATX3.0 Native PCIE 5 Fully Modular 80 Plus Platinum Power supply (SKU: CA-1BW-TT) = £139.99
• 1 x Power Cable for Thermaltake PF3 750/850/1000/1200 Power supply (SKU: CB-001-TT) = £0.00
• 1 x Seasonic Focus GX-750 750W 80+ Gold Modular Power Supply (SKU: CA-06U-SS) = £119.99

Total: £407.96 (includes delivery: £7.99)​

so do you reckon the Thermaltake Toughpower PF3 750W ATX3.0 Native PCIE 5 Fully Modular 80 Plus Platinum Power supply is good enough as i wanted a plat certified psu and this is in my price range any higher than £139 is too much for me. Thanks

I suggested it based on the reviews of the GF3, since I can't find any for the PF3 specifically.
