I'm considering upgrading my roughly four-year-old PC from an ASUS GeForce RTX 3060 Ti DUAL OC V2 to a Radeon RX 9070 XT. Before buying, I want to make sure the new card will physically fit and that my power supply can handle it.
My case is a Svive Halo S650 Midi Tower. The case has a small cable-routing protrusion extending about 2.2 cm from the motherboard tray, and I'm concerned that a longer graphics card might reach it. My current RTX 3060 Ti is 269 mm long and doesn't extend far enough to be affected. The RX 9070 XT model I'm considering is 312 mm long, 50 mm wide, and 130 mm high, while the current card is 52 mm wide and 136 mm high. My rough measurements suggested only about 2.95–3 mm of clearance near the protrusion.
The case specifications list support for graphics cards up to 360 mm long. Does the card's width affect clearance on the motherboard side, or is that dimension mainly about the side-panel clearance? Should I be focusing on the card's height instead?
Also, my current GPU uses one 8-pin connector, while the RX 9070 XT requires three 8-pin PCIe connectors. My ASUS TUF Gaming 750B power supply is listed as having four detachable 8-pin PCIe connectors with removable 2-pin sections. Will that provide the connections I need?

The case’s stated graphics-card limit is 360 mm, so a 312 mm card is within the advertised clearance. GPU width generally describes how far the card extends toward the side panel, while the mounting position and motherboard-side clearance are largely standardized. The protrusion should not be a problem if the case is designed for standard expansion cards, though checking the exact card’s cooler shape is still sensible.
The case manual lists support for up to seven expansion slots and graphics cards up to 360 mm, so the 312 mm card should fit by length. Your power supply’s four PCIe 8-pin connectors should also be enough for a card requiring three 8-pin connections. The removable 2-pin sections are what allow them to function as 6+2-pin PCIe plugs, so check that the required cables are included and available inside the PSU’s cable set.
So those additional PCIe power connectors should already be included with the modular cables? I’ll check the PSU’s cable box and confirm that I have three separate connectors available.
The overall length wasn’t my concern; I was mainly worried about the protrusion extending from the motherboard tray. If the card sits at the same standard distance from the motherboard, then different models should have roughly the same clearance on that side, correct?
