Hey guys, long time follower, first time poster Ive got a pc in that is frustrating the hell out of me. A list of the specs before i start: Intel i7 8700 Asus z390-a motherboard Hyper X (hx432c16pb3k2/16) 16gb ram Dual Channel Kit Evga GTX 1080 FTW corsair h100i rgb watercooling Samsung evo 1tb ssd 3 120mm case fans and the kicker, corsair vs550 power supply. Now my friend brought me the pc saying that it still boots but no video on screen. This happened after a night of heavy gaming. I immediately noticed that the psu is not good enough for all the hardware in his pc. The gpu alone wanting a min 500w psu. If hes gaming and pushing the gpu then surely 550w wont cover it. So first and foremost hes dropped off a new corsair rm750x psu off but alas im still getting the same problem. So ive taken his motherboard out of the case with just the ram, cpu, cooling and psu plugged in. Knowing the cpu has onboard graphics, i reset the bios via the mobo jumper and plugged hmdi into the motherboard. still no video signal. Tried the same again but alternating ram sticks in alternating b2 and a2 slots. still nothing. Furthermore the motherboard has onboard boot diagnostic lights, they light up quickly and go off in turn, even the speaker ive got on the motherboard jumper doesnt give a fault code. To see if the speaker or motherboard wasn't posting correctly i removed all the ram and booted, sure enough the speaker started peeping the no ram code. Ive tried with the gtx1080 plugged in and power now on the 750w psu and tried all of the above, still no luck. To clarify ive plugged my psu tester into the corsair 550w psu and it currently tests fine on all the lines and rails, so it has not blown. If i remember correctly he said the system was about 4-6months old from new. So im fairly sure its a dead mobo but im just not 100% sure, just because those damn mobo post led's think that everything is ok. Am i missing something or can an underpowerd psu break a motherboard, cpu or graphics card when its being pushed.

https://uk.pcpartpicker.com/list/JNkZTH Pricing isnt always correct on part picker though and you need a cooler as your cpu choice does not come with stock.

Im at around £820 and need a case. watercooling is an option later or a decent air cooler if you dont intend to overclock. Overclockers UK Pricelist made 2017-07-26 20.48.pdf

Give me 2 mins to knock something together

Settle on cpu first before mobo

Lol Hahaha yeah, poor client, had they come to me initially i could of done much better. Yup, shes alive and happy behind me with Win10 just finishing install.

So when it comes for me to build pc's for clients im brutal to not allow budget cuts for sake of cheap parts. Im a purely Asus motherboard user, Intel cpus only, Corsair PSU and RAM. WIth your budget i would plum for a decent i5, psu and ram with an asus mobo in a nice case and then whats left get a mid range graphics card with the choice of upgrading down the line

A windows 7 license will still activate 10 like for like, ie Home 7 for Home 10.

got an old windows 7 license lying around?

You got a grand with monitor? so that leaves about 860. you got a windows license?

Lol, its actually easier done than you think if you have a 4 pin mobo and an 8 pin psu but most people check if the plug is in correctly once plugged in. Well its cost them a new psu in the mix, might i add, properly installed lol

Father is adamant his Son is not techy and would never consider opening her up to tinker as its not his type of hobby

its on each response on forums at the bottom of each reply: Main Rig: Intel i7 4790k Devils Canyon 4ghz, Corsair Vengeance Pro 2x8GB 1600MHz, Dual Kingston Savage 240gb SSD's, Asus GeForce GTX 1060 Strix OC Aura RGB 6144MB GDDR5 Graphics Card, Asus H81I-Plus Intel H81 Mini ITX Motherboard, Corsair RM650X PSU, Corsair Hydro Series H100i v2 Extreme Watercooler all in a Thermaltake Core V21 MicroATX Cube Case. Dual Asus 24" VN247H Monitors. Logitech G402 Mouse and Logitech G610 Keyboard.

Even more so, the psu is clearly an 8pin model so they must of through "Sh!t it doesnt fit, lets not try the other connector and just zip it back" I could maybe thing of such stupidity if a kid did his own build (ive seen it, believe me) but not from a pc builder lol

You got it and is totally possible if your a moron lol. You just move the 2 vertical pins left one set and the keys on the plug match up.
